AT&T has also implemented security features directly into the backbone. IP Source Address Assurance is implemented at every customer point-of-entry to guard against hackers. AT&T examines the source address of every inbound packet coming from customer connections to ensure it matches the IP address we expect to see on that packet. This means that the AT&T IP Backbone is RFC2267-compliant.

Thank you, AT&T.
